Air conditioners may look similar, but their Seasonal Energy Efficiency Rating (SEER/SEER2 and EER/EER2) can vary widely. For air conditioners, the Department of Energy’s (DOE) new minimum efficiency standards vary by region, so your choice of AC units will depend on where you live.

The DOE’s regional breakdown by state is as follows:

• North
  • 14.0 SEER/ 13.4 SEER2
• Southeast
  • 15.0 SEER/ 14.3 SEER2
  • 12.2 EER/11.7 EER2
• Southwest
  • 15.0 SEER/ 14.3 SEER2
  • 12.2 EER/11.7 EER2

SEER Versus SEER2

SEER2 is an updated rating standard introduced by the DOE. SEER2 standards are intended to provide a better gauge of typical home operating conditions whereas the older SEER rating utilized very precise protocols to determine ratings in ideal conditions. SEER2 standards include updated testing means that give a better indication of how a unit will operate in the real world.

Much like miles-per-gallon for a car, SEER/SEER2 and EER/EER2 offer an easy way to compare efficiencies of different products – the higher the rating, the more efficient the unit. Just be sure you are comparing either SEER vs SEER or SEER2 vs SEER2 (same for EER/EER2).

EER2 Versus SEER2

EER2 and SEER2 both evaluate an air conditioner’s energy efficiency, but they’re concerned with two different types of temperature conditions:

• EER2 measures an air conditioner’s efficiency at the peak cooling temperature of 95°F.
• SEER2 measures an air conditioner’s efficiency throughout an entire cooling season, with temperatures ranging from 65°F to 104°F.

D & D Refrigeration Can Help You Choose

We currently offer a line of air conditioners that meet the local minimum rating and go all the way up to a 24 SEER2. Depending on your average usage, higher SEER2/EER2 air conditioners can significantly reduce your electric bill.

Additionally, we offer many air conditioners that have advanced features, such as 2-stage compressors and variable speed fan operation. These features not only improve the comfort level of your home but can provide additional energy savings as well. Call us now at 562-428-6421.

Heat pumps are a great solution for your home comfort system when electricity is your only source of energy because they work to provide both heating and cooling. Heat pumps have SEER/SEER2 and EER/EER2 ratings like air conditioners and Heating Seasonal Performance Factor (HSPF/HSPF2) ratings for measuring heating efficiency.

The Department of Energy’s (DOE) new minimum efficiency national standard for Heat pumps is 15.0 SEER/14.3 SEER2/11.7 EER2 and 8.8 HSPF/7.5 HSPF2. This is a standard across the United States. Higher SEER/SEER2 and HSPF/HSPF2 ratings mean greater energy savings.

Let D & D Refrigeration Walk You Through All The Heat Pump Choices

Heat pumps are a very efficient alternative to electric baseboard heat alone. A heat pump works the same as an air conditioner in the summer, but it runs in reverse in the winter to heat your home. If needed, the system will be matched with a backup heating source, most often electric strip heating elements, for those extremely cold days of winter.

Just like our air conditioners, many of our heat pumps have advanced features, such as 2-stage compressors and variable speed fan operation. These features not only improve the comfort level of your home, but can provide additional energy savings as well. Call us now at 562-428-6421.

Today's new high efficiency furnaces can save up to 50% in operating costs over a ten-year-old furnace. Many 1990 and earlier model furnaces have Annual Fuel Utilization Efficiency (AFUE) ratings of 65% or less. The minimum AFUE rated furnace that can be sold in the United States today is 80% for the Southeast and Southwest, with 90% being the minimum in the North.

Our current product offering starts at 80% AFUE and goes all the way to a very efficient 98%+ AFUE rating. Depending on your average usage, higher AFUE rated furnaces can significantly reduce your gas bill.

The DOE’s regional breakdown by state is as follows:

• North – 80% AFUE
• Southeast – 90% AFUE
• Southwest - 90% AFUE

Let D & D Refrigeration Help Pick The Right Furnace For Your Home

We offer many furnaces with variable and multi-speed features that can provide enhanced indoor comfort by slowly ramping up to your thermostat setting rather than simply turning on at full speed. This alleviates the "cold air blow" often associated with single speed furnaces, and dramatically reduces system noise. Call us now at 562-428-6421.

Thermostats are used to turn on heating or cooling systems to bring the home to a set temperature. In addition to basic temperature control, programmable thermostats can be used to manage the indoor environment of your home at different times of the day or week. This type of control can have a dramatic impact on the overall energy use of your home. We carry a complete line of thermostats. Let us help you choose the one that best matches your lifestyle.

The air handler is the indoor component of a heat pump system. It includes the fan and the heating/cooling coil. The air handler is designed for a particular refrigerant, so it must be matched with the heat pump or air conditioner.

We offer many air handlers with variable and multi-speed features that can provide enhanced indoor comfort by slowly ramping up to your thermostat setting rather than simply turning on at full speed. This alleviates the "cold air blow" often associated with single speed air handlers, and dramatically reduces system noise.

Our oil furnaces use no.2 fuel oil burned in a sealed chamber to heat an exchanger.  Just like gas furnaces, oil furnaces also carry AFUE ratings and start at 80% AFUE.

Our complete line of packaged systems include Packaged Air Conditioners, Packaged Gas Furnaces and Air Conditioners, Packaged Heat Pumps and Packaged Hybrid Heat. These self-contained systems are located outside of the home, mounted on the ground or the roof, and ducted into the home.

Just like individual furnaces, air conditioners and heat pumps, these package units carry SEER/SEER2, EER/EER2, AFUE and HSPF/HSPF2 ratings. The higher the rating, the more energy efficient the unit is. The Department of Energy’s (DOE) new minimum efficiency standards vary by region, so your choice of package units will depend on where you live.

Zoning can provide optimum comfort with increased energy savings in your home by dividing a home into areas with similar heating and cooling needs and independently controlling the temperature in each area. Much like multiple light switches that independently control lighting in different rooms, with zoning, multiple zone thermostats or sensors control temperature in different areas of the home. Contact us for an in-home evaluation and estimate.

Air cleaners effectively remove bacteria, pollen, animal dander and other pollutants as small as 0.01 microns. That's 18,000 times smaller than the head of a pin. The higher the Minimum Efficiency Reporting Value (MERV), the more efficiently the cleaner removes particles. We offer air cleaners that range from MERV 10 to MERV 15 to meet your needs.  For those families that have severe allergies, we also offer Whole House High Efficiency Particulate Arresting (HEPA) filtration systems.

Humidifiers work in tandem with your heating system to deliver desired humidity levels throughout your home. Maintaining proper humidity levels in your home is essential to maintaining indoor comfort during the winter months. Moderate humidity levels make you feel warmer at lower temperatures, which means you can set your thermostat lower without sacrificing comfort.

Depending on the size of your home, we offer a variety of humidifiers to deliver the right amount of moisture into the air. Sizing of humidifiers is measured in Gallons Per Day (GPD), and we offer models from 12 GPD to 18 GPD.

Ventilators bring fresh air into your home without losing heating or cooling energy. Their unique energy exchange system transfers the heating or cooling energy from the stale air being exhausted from your home to the fresh air the ventilator brings into your home.

If your family suffers from allergies, ventilators are a much better alternative for introducing fresh air into your home versus opening your windows. They also do a great job of reducing cooking and pet odors, smoke and other pollutants out of your home. 

How it works:

• Internal air intake - draws in stale indoor air, directing it through the heat exchanger core.
• External air intake - draws outside air, venting it through the air filter.
• Internal air exhaust - vents indoor air outside from the heat exchanger core. Up to 84% of the indoor heat has been removed, helping minimize utility costs.
• Fresh air exhaust - vents conditioned, heated outdoor air into your living areas.
• High efficiency heat recovery core - extracts heat from stale indoor air and transfers it to fresh outdoor air for maximum comfort with little heat loss. This core also removes excess humidity from recirculated air - lower humidity levels help you stay comfortable at higher temperatures in the summer and lower temperatures in the winter.
• Ventilator motor - moves air through the system efficiently and quietly.
• Air filter - cleans outdoor air of small particles before they circulate through your home.
• Electronic circuit board - adjusts air circulation modes and motor speeds.
• Damper defrost - helps prevent frost from forming within the system, eliminating the need for a supplemental energy -consuming electric defroster. This defroster engages when temperatures drop below 23 degrees Fahrenheit.
• Briefcase-style exterior latches - allow easy filter changes with no tools required.
• Simple wall control - makes operating the HRV easy and convenient.

Ultraviolet light kills bacteria and mold growing on your indoor coil before they are circulated throughout your home. UV lamps are installed near your existing indoor coil and work diligently to rid your home of the bacteria, viruses, mold and germs that impact your home's health. We install 1 or 2 lights per indoor coil, depending on the size of the coil.

Carbon Monoxide (CO) is a colorless, odorless, and tasteless gas which makes it extremely dangerous. CO detectors can protect your family from deadly carbon monoxide gas. Fuel-burning appliances such as oil and gas furnaces, gas water heaters, gas ranges and ovens, gas dryers, gas or kerosene space heaters, fireplaces and wood stoves are all sources of carbon monoxide.

A monitored carbon monoxide detector will alert you if high levels of this deadly gas are detected. Local building ordinances require the installation of carbon monoxide detectors in your home. An expert technician from D & D Refrigeration can properly install your CO detector and ensure it's functioning correctly.
